The grand wazoo, section. Transcription: KS (bars 1-12 and harmony/bass fill in from bar 13 onwards)/Wolfgang Ludwig (basic melody from bar 13 onwards).
Ludwig part published in 1992, KS: update 2007, deposited at the I-depot The Hague.
Note: via the Think it over score (see below in the Grand Wazoo section) I noticed Zappa had composed beat 3 of bar 13 etc. as a quintuplet.
